.1 Specification of Letters Patent.

Patented July 3, 1908 Application filed August 24, 1805. Serial Ho.3%,691.

To all whom it may eoztcern: K 7 7 Be it knownthat I, J UmANCHAaLEs BUR-more, Jr. a citirlen of the United-States, and

my invention is the provlsion-of'an' elastic tire having' greatresilieney and durability and increased adhesion under certainconditions for purposes cjf' traction and the prevention of skidding. K

Other objects are to provide a tire of sec tion'al construction for thesake of economy'- and ease of replacement or repair of damgiged 7 parts,to one le it to be readily 'ada various styles of rims or *fellies andmodes of attachment, and to fivide suitable in The advanta es of myinvention are more may. set forth ereinafterl with reference to theaccompanying drawings of an exemplifying structure 11;. whichfthe saidinventlon is embodied, and in which- A Figure 1 is a cross-sectionalview of such a structure; F1 2 is a side elevationof a portion of awheel elly, rim, and tire. plan View of a. portion of a tire, showingortions of two tire-sections andmy interloc j g connection therefor; andFig. 4, a detail view In the drawings reference-numerai 1 myftire may bereadily ada ted, but which may be rgglaced byrnanyot or forms of rimsoromitt altogfigrer in which case the tire wonldbeattac directly to thefell 3, the inwardly tmned clencher ed es '0 the rim; 4 the tireconsidered as awho e, usually of tub or a rubber composition; 5, the 6,the tread, 0 .an desired sectional she e, but preferably roun ed, as inFig, 1; 7,110 lowed portions or recesses formed in the'sides of thetire, preferabl extending approximately tothe rim or fol y andintersecting the tread at a point somewhat removed from its normalgreatest dircumference and preferabl also pieced oppositely on the twosidesof t e tire, although theformsarid arrangement of these recessesare not material; 8, grooves, one provided-in one end of eachtire-section 9, tongues, one on the. end of each section opposite to itsgrooved end and adapted to enter the groove g'the same to the Fig. 3 isa in the adjoining section, the tongues? A 7 "grooves 8 constitutinginterlockingf eonnec other; 30, a central longitudinal cleft or slotformed in the base of each section, leaving the base bifurcated, eachpart of the base beingprovided with an outwardlypresentmg hooked member10' to engage the correspoa hookin the rim; 11, an enlargernent w ch maybe placed centrally in each slot 10 to accommodate the locking-bolts,

having perforations 12*,embedded in the tii'esections, one near'theinner surtace of each part of the bifurcated base; 13, bolt lugs "one oneach strip 12, the two iugs of, each seo' tion being placed oppositeiand each lug preferably extending outwar l'y slightly from the trails ofthe tire, as sh we, on being laceommodated in the rim bi properlyforming or cutting recesses for t clencher edges 3 of the-rim one forcan tire-section, hav left threadsengaging correspon mg threads.r

Many merits o the present invention art apparent to those skilled in theart without further description, but some of them will be. particularlypointed out. The

too

when under (ZOIHPTBSSIGB. lo tudjpall great extent as well as Iater fil",fand so on slippery road-surfaces and in snow and slush serve toincrease traction and. revent side'- l slipping. The tire is readily anquickly 88-" base, are drawn together, and by op oeite'" section is putin place in the rim by taming and tions for securing'the-tire-soctionsto each but is not indispensable; 12, metal strips,

rig t and in the two iugs 13 of each section so that by turning the boltin one direction the lugs, and

belts lifi'fifloek-nuts on the opposite cnds (if the bolts for lockingthe same when propdraw the base portions of the section together j Vsufficiently to enter the rim and placing the.

the rim and further secured against displacethe tire permit an expansionof the -1ubber sembled. Serious damage to one section only necessitatesits removal and replacement by a spare part and does not retire the tirefrom service during repairs.

While all the parts of the invention described cooperate to greatadvantage in a com lete tire structure, yet some of them as, orinstance, the'attachment device and the sectional and recessed structureof the tire properpossess important novel features apart from theothers, and I contemplate the use ofall such novel features of thisinvention in any cases Where they may be advantageous y employed, eitherseparately or in combination with one or more of the other of saidfeatures.

What I claim is- 1.' A wheel-tire comprising a plurality of sectionshaving interlocking abutting faces so shaped as to resist relativelongitudinal movement of the sections.

2. A wheel-tire com risin a p urality of sections having interloc 'ngaut .igi res so shaped as to revent relative longitudinal movement of thesections extendin radially from the rim to the tread, and see sectionhaving a plurality of recesses formed in its sides, intersecting thetread. 3. In a wheel, the combination of a rim having hooked edges, anda tire composed of a "plurality of sections, each bein formed with alongitudinal basal recess and ha vinia hook on each base portion formedthere y for engaging the corresponding rim-hook, a metal strip ineachbase portion bearing a lug, and a right and left threaded bolt engagingsaid lugs. 1

4. In a wheel, the combination of a rim having hookedfledges, and a tirecomposed of a plurality of sections, each being formed with alongitudinal basal recess andhavin a hook on each base portion formedthere y for engaging the corresponding rim-hook, a

metal strip in each base portion bearing a lug a right and left threadedbolt engaging said lugs, means for turning said bolt, and a locknutthereon.

5. A tire adapted to a clencher-rim, comprising a number of sections,each having radially extending interlocking members so formed as toreven't relative longitudinal movement of t e sections, a bifurcatedbase a clencher member on each base portion, and mechanical means forforcin said clencher members into engagement wit the clencherrim.

' 6. In a tire, a lurality of sections having a tread of roundscrossssection, and recesses formed opposite each other in opposite sidesof each section and intersectin the tread.

-7. A tire, compris' a plum 'ty of sections of flexible or compressl ismaterial, each havin a double base .ortion, a longitudinal meta ie stripin each ase portion provided with an internal screw-threaded part, abolt with right and left hand threads engagin the screw-threaded partsof said strips, an longitudinal hooks formed on the outer side ofeach'base ortion,-adapted to engage cooperating rimooks.

8.. In a tire, a luralityof sections having a tread of roun ed crosssection, recesses formed opposite each other in opposite sides of eachsection and intersecting the tread, and a fastening device comprising adoublethreaded bolt engag' metallic members carried in the base of onesection, for locking the same to a cooperating clenehen-rim.

In testimony whereof I have afiixed my name heneunto in the presence oftwosut scribing witnesses.
